Definitions

  • the invention relates to a rotary spinning electrode of elongated shape, serving to carry the solution or melt of polymer matrix from a reservoir into an electric field for spinning in devices for production of nanofibres through electrostatic spinning of solutions or melts of polymer matrixes, comprising a pair of end faces, which are arranged on a carrying mean, and between which spinning cords or wires are mounted.
  • the device comprises the spinning electrode in the shape of a cylinder, which rotates around its main axis and by lower section of its surface it soaks into the polymer solution.
  • the polymer solution is by a surface of the cylinder carried into the electric field between the spinning and the collecting electrode, where are created nanofibres, which are carried towards the collecting electrode and in front of it they deposit on a substrate material.
  • This device is very well capable of production of nanofibres from water polymer solutions, nevertheless the layer of nanofibres applied on the substrate material is not uniformly spread along the whole length of the spinning electrode.
  • DE 101 36 255 B4 discloses a device for production of fibres from polymer solution or polymer melt, which comprises at least two spinning electrode mechanisms, each of them formed by a system of parallel wires mounted on pair of continuous belts embraced around two guiding cylinders, which are positioned one above another, while the lower guiding cylinder extends into the polymer solution or polymer melt. Between these two spinning electrode mechanisms a textile is passed as a counter electrode, while the spinning electrode mechanisms simultaneously create coating both on face side as well as backside of the textile.
  • the spinning electrode is together with the counter electrode, which is formed by an electrically conductive circulating belt, connected to a source of high voltage.
  • Polymer solution or polymer melt is carried by means of wires into electric field between the spinning electrode and the counter electrode, where from the polymer solution or polymer melt are produced fibres, which are carried towards the counter electrode and land on the textile positioned on the counter electrode.
  • a long time of staying of polymer solution or polymer melt in the electric field represents a disadvantage, because the polymer solution as well as the polymer melt are subject to ageing quite quickly, and changes its properties during the spinning process, which results also in changes of parameters of produced fibres, especially of their diameter.
  • WO 2008/028428 discloses a rotary spinning electrode of elongated shape for device for production of nanofibres through electrostatic spinning of polymer solutions, which comprises a pair of end faces between which there are mounted spinning members formed by wire, which are distributed evenly around the circumference and parallel with axis of rotation of the rotary spinning electrode.
  • the end faces are made of electrically non-conducting material and all the spinning members are mutually connected in electrically conductive manner.
  • the spinning members mounted parallel with axis of rotation of the rotary spinning electrode ensure good conditions for spinning in electric field, nevertheless upon their exit from solution or melt of polymer, the polymer solution or polymer melt is splashed, especially at lengths of electrodes above 0.5 m, due to surface tension of polymer solution or melt, because the whole length of the spinning member emerges above the solution level in one moment.
  • the goal of the invention is to preserve good conditions for spinning and to eliminate the splashing upon exiting the spinning member from solution or melt of polymer.
  • the goal of the invention has been achieved through a rotary spinning electrode according to the invention, whose principle consists in that, spinning cords or wires are in a skew position to axis of rotation of the rotary spinning electrode. Due to the skew position, the spinning cord or wire emerges from the solution or the melt of polymer matrix gradually, so that no splashing occurs even at lengths of the spinning electrode over 1 m.
  • the ends of the spinning cords or wires are on both end faces mounted in the same distance from the axis of rotation.
  • the end faces are made of conductive material. At this solution it is sufficient, if the electric voltage is supplied into the solution or the melt of polymer matrix and due to conductivity of end faces, whose part is still in the solution or the melt of polymer matrix, are all the spinning cords or wires under voltage.
  • the spinning cords or wires of rotary spinning electrode are formed of one continual cord or one continual wire, while at least one end face is adjustable in direction of axis of rotation of the rotary spinning electrode and is coupled with the stretching mean.
  • the stretching mean is formed of a stopper fastened between the end faces and a pressure spring arranged between the stopper and the adjustable end face.
  • the stopper has a shape and size of the end face and it is provided with openings for passage of the spinning cords or wires to the adjustable end face on which they are fastened.
  • the spinning cords or wires are mounted independently on the end faces, and to each spinning cord or wire, there is assigned at least one individual stretching mean.
  • the individual stretching mean is with advantage formed of a pressure spring arranged between the corresponding end face and an end member fastened at the end of the spinning cord or wire.
  • Rotary spinning electrode according to the invention is schematically represented in the enclosed drawing, where the
  • FIG. 1 represents an axonometric view on the rotary spinning electrode.
  • FIG. 2 shows an embodiment with stretching members formed of one cord or wire with stretching means.
  • FIG. 3 shows an embodiment with independent stretching members and central stretching means.
  • FIG. 4 shows an embodiment with independent stretching members and individual stretching means.
  • Rotary spinning electrode comprises carrying mean 1 , which is in the represented embodiment formed of a shaft, on which are, perpendicular to its longitudinal axis 11 , which is at the same time axis of rotation of the rotary spinning electrode, mounted end faces 2 , 3 .
  • the carrying mean 1 may be formed for example of a tube or other suitable body. In example of embodiment according to the FIG.
  • both end faces 2 , 3 are of the same diameter and along their circumferences there are evenly created grooves 21 , 22 , 23 , 24 , 25 , 26 ; 31 , 32 , 33 , 34 , 35 and 36 , in which a cord or wire 4 is mounted, while the sections of the cord or wire 4 tight between the end faces 2 , 3 form spinning members 41 , 42 , 43 , 44 , 45 , 46 .
  • the end face 3 is turned towards the end face 2 , so that the spinning members 41 , 42 , 43 , 44 , 45 , 46 are skew to the axis 11 of rotation of the spinning electrode.
  • Ends of the spinning members 41 , 42 , 43 , 44 , 45 , 46 are on both end faces 2 , 3 mounted in the same distance from the axis of rotation.
  • the end faces 2 , 3 are made of conductive material.
  • the spinning members 41 , 42 , 43 , 44 , 45 , 46 are formed of one continual cord or wire 4 . According to the FIG. 1 the cord or wire 4 is fastened on the fixed end faces 2 , 3 .
  • one end face 2 is fixed and the second end face 3 is mounted axially adjustable on the carrying member 1 .
  • the carrying mean 1 mounted in a fixed manner a stopper 5 , between which and the adjustable end face 3 there is mounted the pressure spring 6 .
  • the stopper 5 is of the same shape and size as the end face 3 and is provided with openings or grooves for passage of the cord or wire 4 forming the spinning members 41 , 42 , 43 , 44 , 45 , 46 .
  • the spinning members 41 , 42 , 43 , 44 , 45 , 46 are formed of individual cords or wires 4 .
  • the FIG. 3 is in the same manner as in the embodiment according to the FIG. 2 one end face 2 fixed and the second end face 3 mounted axially adjustable on the carrying member 1 .
  • the stopper 5 Between the end faces 2 , 3 there is on the carrying mean 1 in a fixed manner mounted the stopper 5 , between which and the adjustable end face 3 there is mounted the pressure spring 6 .
  • the stopper 5 is of the same shape and size as the end face 3 and is provided with openings or grooves for passage of cords or wires 4 forming the spinning members 41 , 42 , 43 , 44 , 45 , 46 .
  • the diameter of the stopper 5 is smaller than the diameter of the end face 3 .
  • all individual spinning members 41 , 42 , 43 , 44 , 45 , 46 are stretched by one adjustable end face 3 and the pressure spring 6 , which imposes great demand on very identical length of individual spinning members 41 , 42 , 43 , 44 , 45 , 46 .
  • the end faces 2 , 3 on the carrying mean 1 may be adjusted in a simple way.
  • the carrying member 1 may be provided with fastening openings of constant spacing. Then, the user has possibility to adjust the distance of end faces 2 , 3 according to the width of material being processed.
